This sounds like you changed the driver, so change the binding. That 
would be an ABI break. But it looks like you are adding support for new 
h/w, so say that. Bindings aren't about a driver.

Do we really need new names? Was 'aclk' not the bus master clock?

If the clocks and resets aren't the same, then maybe these 2 new chips 
should be their own binding.

'rst_' is redundant, drop.
